I've never seen this happen before. The aluminium core LED panel has actually delaminated. I don't know the full history of this light as it was sold as untested, although a flex had been Wago'd onto the original wire stubs! So hopefully it wasn't powered up with a saturated electronic driver.
As supplied it was covered in mud and had water in the LED section, suggesting it had been stood vertically outdoors for a while, with the pole port up.

It's possible that the standing water and a number of freezing cycles caused progressive delamination, and the submersion may also have resulted in humidity ingress to the LEDs too. So I don't know if the light was retired due to LED failure or if that happened in outside storage. It's not old, so it must have been removed for a reason.

If you work with these lights (Urbis Schreder Axia 2?) then let me know if you have had issues with them.
